SIGNORS, BY MESNE ASSIGNMENTS, TO THE JAEGER MACHINE COMPANY, OF

COLUMBUS, OHIO, A CORPORATION OF OHIO TOWER Application filed December9, 1927.. Serial no. 238,800.

This invention relates to towers, such as are used by contractors inconnection with the hoisting and distribution of concrete or othermaterial, and it has particular reference to sectional steel towers andcertain details entering into the construction thereof.

Towers of the type referred to are adapted to be erected on differentjobs, being dismantled and moved from one place to another as conditionsrequire,'and are exposed to all sorts of weather conditions. As a resultof this exposure the bolts which hold the members in assembled relationfrequently become rusty so that their removal is rendered very ditficultand requires an undue expenditure of time and labor.

An object of the present invention isto provide a tower which can bereadily assembled and disassembled, and one in which the securingmembers arev protected from exposure to the elements.

Further objects and advantages to be de rived through practice of theinvention will become apparent from a perusal of the followingspecification describing a preferred embodiment thereof. taken inconnection with the accompanying drawings illustrating the invention.wherein- Fig. 1 is an elevational view illustrating the upper and one ofthe intermediate sections of our improved tower, the horizontals anddiagonals of only one side of the tower being shown;

Fig. 13 is a horizontal sectional View taken I of sections, eachcomprising four uprights or columns 10 arranged in square formation andsecured in spaced relation by means of girts 11, the structure beingreinforced by means of diagonal braces 12, hereinafter termed diagonals,arranged on all four sides of the tower. Each of the sections is abouttwenty feet in length and when assembled includes approximately fourgirts on each side with pairs of diagonals arranged, as illustratedFigs. 1, 7, 8, 9 and 10, between adjacent girts on each side of thetower. be noted that the girts on one pair of diametrically oppositesides of the tower are arranged at a slightly different level than arethe corresponding adjacent girts on the other pair of diametricallyopposite sides, as clearly shown in Figs. 7, 8 and 9. Elevator guides 13are provided on two opposite sides of the tower, being secured to thegirts midway of the ends thereof in a manner to be described presently.

In some instances it is found desirable to use two elevators side byside, in which case six uprights or columns 10 are arranged to form twosquares, the middle tier ofgirts carrying elevator guides for bothshafts, as illustrated in Fig. 3.

As hereinbefore stated, trouble has been experienced in loosening thebolts which secure the different members, due to corrosion of thethreaded portions, which has often resulted in great loss in time andlabor in the dismantling of the tower. With the view to the eliminationof such disadvantages, we have illustrated in Figs. 1, 7, 8, 9 and 11the It should improved means which our invention provides for securingthe girts and diagonals to the columns.

Referring particularly to Fig. 11, each girt 11 has its ends closed bymeans of a plug 17, having a reduced portion 18 which enters the end ofthe girt and is spot welded or other wise secured thereto at one or morepoints. The plug 17 is formed with a centrally disposed threadedaperture 1'? which is flared outwardly at its outer end to facilitatethe proper starting of the bolt therethrough. The end of the plug isalso formed with an are shaped transverse concavity 17 corresponding tothe outer surface of the column 10. At the points where the girts are tobe secured the columns 10 are provided with diametrically alignedapertures 20 adapted to receive bolts 21 which are passed therethroughand which enter the threaded apertures in the plugs 17 in the ends ofthe girts, the recesses 17 fitting snugly against the columns and theflared threaded portions serving to guide the bolts into properposition- The diagonals 12 are formed with flattened end portions 12which are apertured to receive the bolts 21, a pair of diagonals beingcarried by each bolt adjacent the head thereof and between the head ofthe bolt and the column 10. A diagonal is secured to each of the bolts21 at the top of the tower and extends downwardly diagonally across itsrespective side of the tower, being secured to the next lower belt ofthe other column 10 of that side. Of course, the intermediate bolts 21each form the securing means for two of the diagonals, as illustrated inFigs. 1, 7, 8 and 9. As previously stated, the horizontal girts on onepair of opposite sides of the tower are at a slightly diflerent levelthan are the corresponding girts on the other pair of opposite sideswith the result that the bolts 21 pass through the tower in pairs, thebolts of each pair being disposed at right angles to each other with onebolt located above the other (see Figs. 1, 7, 8, 9 and 10). It will beappreciated that only the heads of the bolts 21 are exposed, the threadsbeing entirely protected so that even though the structure may stand foran indefinite period no trouble will be experienced in loosening thebolts when desired.

In Figs. 3, 4, 5 and 6 we have illustrated the manner in which theelevator guides are secured to the horizontal members or girts. Theguides 13 are formed of sections of tubular metal, the sections being ofsuch length that the joints therebetween always fall opposite one of thegirts. Each of the guide sections has secured to one end, preferably bywelding, a curved plate 22 having a threaded aperture in alignment witha similar aperture adjacent the end of the guide. The plate 22 is ofsuch length as to project beyond the end of the guide sectionand intothe next succeeding section of the guide. It

is, of course, necessary that the inner opposed faces of the guides beuninterrupted so as to form a track for the elevator, and to this endthe securing means is located inside the tube which forms the guide. Theguide is spaced relatively to the girt by means of a spacer 23, whichconsists of a short tubular member having its ends cut away so as toengage snugly the girt and the guide respectively. Bolts 24 are passedthrough aligned apertures in the girt, the threaded portions enteringthe threaded apertures in the plate 22. Thus each section of theguide-way is locked securely to the preceding section until the desiredheight is reached, and as in the case of the girts and diagonals thethreaded portions of the bolts are entirely protected from exposure.

In the double shaft construction, that is to say where two shafts areerected side by side, the middle tier of girts support elevator guidesfor both shafts in a manner now to be described.

Referring particularly to Figs. 3 and 4 of the drawings, whichillustrate the means for connecting the guides in the double shaftstructure, the numeral 25 designates a member formed preferably of castiron metal and comprising portions 26 and 27, each being provided withan arc shaped outer surface 28. The portions 26 and 27 are off-set withrespect to each other and are provided with apertures adapted to receivebolts which extend into the threaded apertures in the plates 22 andserve the double function of securing the guides to the girts andlocking the guide sections in assembled relation.

It is necessary to provide landings for the elevators at certain pointsalong the shaft and at these points, as a measure of safety, socalledlanding panels are secured. One of these panels is illustrated in thelower portion of Fig. 1 of the drawings, and the means employed in themounting thereof is illustrated in Fig. 12. The landing panel comprisesa rectangular frame having braces extending diagonally from its cornersat opposite ends. The panels are secured at their ends to the columns 10by means of U-bolts 29, which embrace the columns and extend throughapertures formed in a flange member 30, having a reduced portioni3lwhich enters the end of the tubular horizontal frame member 11?) and ispreferably spot welded thereto.

After a sufiicient number of sections have been joined together to givethe desired height to the tower, a top section is mounted thereon, asillustrated in Figs. 10 and 13. The top section is relatively short andincludes posts or columns 32, similar to the columns 10, each beingsurmounted by a cap 33 for preventing moisture from entering the ends ofthe columns. The cap is secured in position by means of bolts passingthrough i...

aligned apertures in the column and the cap. The top section is providedadjacent its upper end with rails 32a formed of channel iron, whichextend entirely around the tower and are secured to the columns 32 bymeans of U- bolts 34 and also by means of bolts 35 which are passedthrough aligned apertures in the columns and the web of the channel.Reinforcing plates or bars 86 positioned between the channel and thecolumns provide a rigid bearing between these parts. The lower ends ofthe column 32 are provided with sleeves 37 (shown in dotted lines inFig. 10) which extend into the tops of the columns 10, so that thissection may be readily lifted out when it is desired to dismantle thestructure.

It will thus be apparent that our invention provides a tower which isextremely simple in construction, which may be quickly and easilyerected or dismantled, and one in which the threaded portions andmembers are so positioned that they are not subjected to exposure to theelements.

Although preferred embodiments of the invention have been illustratedand described herein, it should be understood that the invention issusceptible of various modifications and adaptations within the scope ofthe appended claims.
